What's especially curious about this story is that he's a libertarian who did a bunch of work for the government. News flash: (real) libertarians don't like the government. Odd.
I don't like the government, but still use the library. My point is libertarians are (typically) much more committed when it comes to principles. It's one thing for a libertarian to use public roads - he has no choice if he wants to live. But voluntarily working for the government is actively supporting evil to a (real) libertarian. Unless they're attempting change from the inside, I don't expect you'd see it much. Yet Satoshi has government written all over his background. Perhaps that's why the majority (all?) of politics are made up of unprincipled people.
I understand the argument "a man's gotta eat." And it's possible he wasn't always a libertarian. But once you've subscribed to the philosophy (and I'd argue that, of all the political persuasions, except maybe anarchism, libertarians are the most grounded in principles), I can't imagine the money matters relative to making a deal with the devil.
